Abstract (en)
[origin: US2020285479A1] A data processing apparatus includes obtain circuitry that obtains a stream of instructions. The stream of instructions includes a barrier creation instruction and a barrier inhibition instruction. Track circuitry orders sending each instruction in the stream of instructions to processing circuitry based on one or more dependencies. The track circuitry is responsive to the barrier creation instruction to cause the one or more dependencies to include one or more barrier dependencies in which pre-barrier instructions, occurring before the barrier creation instruction in the stream, are sent before post-barrier instructions, occurring after the barrier creation instruction in the stream, are sent. The track circuitry is also responsive to the barrier inhibition instruction to relax the barrier dependencies to permit post-inhibition instructions, occurring after the barrier inhibition instruction in the stream, to be sent before the pre-barrier instructions.
